An exemplary embodiment builds on the idea of presence and SIP messaging in conjunction with a profile comprising, for example, a lookup table and a rules module, to assist with one or more of reminders, actions, endpoint maintenance, availability, endpoint capabilities and session management. A catheter having an elongate shaft can include removable support means that can provide column support to the elongate shaft. A recipient control point in the device connectivity architecture can then determine whether announcements of different addresses for the device or service are in addition to a previous announced address, or supercedes any previous announced address. A hollow cylindrical connecting stub is provided on the molding such that it protects in the axial direction, and can be placed against the cable sheath from the inside of the cable.
